Hello. Please look at the manufacturer of the testing machines. You can send them an inquiry to get more information. You can either choose the wide wheel abrasion test or the Böhme test in accordance with BS EN 1338 and BS EN 1339 or Abrasion Resistance of Concrete by Sandblasting in accordance with ASTM C418. If you need any additional information, please feel free to contact me. www.testing.de/en www.formtest.de/en/

Thank you and I am glad this video helped you.

@@JoelSanthosh89 sir i need help you

I'm always been confusing while abrasion testing like placing of sample in machine means how to complete 16 cycle

Abrasion Testing Machine as described in Annex F of IS 1237 and Annex E of IS 15658. It is also called as Böhme disc abrader in accordance with BS EN 1338 and BS EN 1339.

Loss in volume after 16 cycles shall be less than or equal to: a. 18000 mm3/5000 mm2 - In areas subject to very heavy pedestrian and vehicular traffic. b. 20000 mm3/5000 mm2 - In areas subject to normal pedestrian and vehicle use.

Sir plz ...which teats make on paver block

@@JoelSanthosh89 sir, is there any standard reference or code available for abrasion resistance values...for paver blocks...i have IS 15658: 2006 with me. But could not get any idea on the desirable values for paver blocks

@@amalsworld623 Hello, Please refer to the standard specification BS EN 1338:2003, Böhme test (annex H) Table 5. Alternatively, measured in accordance with the test method described in annex G, Wide Wheel Abrasion test.

did u make the report?

Hello Hafiz. Greetings to you! Glad to hear from you. I do appreciate your question. Referring to the standard specifications IS 15658: 2006, IS 1237:2012 and BS EN 1338:2003/BS EN 1339:2003, the grinding path of the disc of the abrasion testing machine shall be evenly strewn with 20 g of the abrasive powder. The specimen shall then be fixed in the holding device with the surface to be ground facing the disc, and loaded at the center with 294 ± 3 N. The grinding disc shall then be put in motion at a speed of 30 rev/min and the abrasive powder is continuously fed back on to the grinding path so that it remains uniformly distributed in a track corresponding to the width of the test piece.

@@JoelSanthosh89 what is the name of this machine?

The standard abrasive used shall be fused alumina (artificial corundum). The abrasive powder shall have an aluminium oxide content of not less than 95 percent by mass. The specific gravity of the grains shall be between 3.9 to 4.1. The grains shall generally have a hardness of 9 in Moh’s scale. Conformity with these requirements, the homogeneity of the material and the uniformity of bulk density and grading of the abrasive shall be checked.

Use square slabs or cubes with an edge length of (71,0 ± 1,5) mm as specimens. The contact face and the opposite face of the specimen shall be parallel and flat. The opposite face shall, if appropriate, be ground parallel or otherwise machined so as to be parallel.

Sir how to calculate PR density of specimen
